SIPHON-HEAD.

Patented Jan. 11, 1916.

Application filed April 28, 1915. Serial No. 24,116.

To all whom it may concern:

Be it known that I, CHARLES DE LUKAC- snvros, a citizen of the United States, residing at Vest Nutley, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Siphon- Heads, of which the following is a specification.

This invention relates to siphon heads and has for its object to produce an improved device of the character mentioned which is inexpensive to manufacture and whose parts are easily assembled, dismantled and accessible for cleaning, etc.

One object of the invention is to construct the device in such a manner as will render the same wholly sanitary.

One feature of the invention is to provide a siphon head with a removable cap which permits access to the valve mechanism and removal of the parts from the head. The removable cap is also provided with a guideway which receives the upper end of the valve stem.

Another feature of the invention is to provide an operating lever formed with an aperture intermediate its ends and having one end extended into the head and-pivotally held therein; and by having the'stem of the valve extending through said aperture, thus retaining the operating lever in position; and by providing adjustable bearing plates for the end of said lever which hold the whole organization in proper operative position.

Other features of construction will appear as the description of the invention proceeds and will be finally pointed out in the appended claims.

In the drawings which form part of the specification: Figure 1, is a fragmentary, vertical section of a siphon head constructed in accordance with the invention and illustrating the operating parts thereof; Fig. 2 is a plan view of the siphon head with the top and valve mechanism removed therefrom, a portion being broken away to illustrate its interior construction; Fig. 8 is. a detail sectional view of the removable cap of thesiphon head, Fig. 4 is a plan view of Fig. 3; Fig. 5 is a detail View of the operating lever disclosed in Fig. 1; Fig. 6 is a plan view of Fig. 5; Fig. 7 is a vert1 cal sectional view of a modified form of the invention; Fig. 8 is a detail view ofv the operating lever shown in Fig. 7 Fig. 9

bore

isa fragmentary plan view of Fig. 8; and F1g. 10 is a detail view of the valve stem shown in Fig. 7.

Like reference characters denote similar like parts throughout the specification and drawings.

Referring particularly to Fig. 1 wherein the preferred embodiment of the invention is illustrated, 1 denotes the body portion of the siphon head and is adapted to be secured to the top or neck of a bottle or jar 1n the usual or any approved manner. The body portion 1 is formed with an internal 2 extending longitudinally therethrough. The bore is reduced intermediate its ends by the shoulder 3 and has communieating therewith at its upper end a slot 4 which extends downwardly for a distance from the upper edge of the body member.

The wall of the bore is also formed diamet rically opposite said slot with a recess or cavity 5, and as here shown, is comparatively smaller than the opening provided by the slot 4. The upper end of the body memher 1 is provided with a threaded extension 6 adapted to have removably threaded thereupon the cap 7 adapted to close or seal the upper end of the body 1. A valve 8 is disposed in the lower end of the body 1 adapted to cooperate with its seat 9 for controlling the passage of liquid siphoned to the bore 2 in the head and discharges through the passage 10.

7 An operating lever 11 is provided for controlling the operation of the valve 8, and has the spherical end 12 extended through the slot 4 into the body 1 and placed in the cavity 5, wherein the end 12 is loosely retained or held and provides a fulcrum for the lever 11. Extending through'the bore 2 is the valve stem 13 adapted to enter and extend through the aperture 14 formed in the lever 11 intermediate its ends. The aperture is of suiiicient size to permit a slight rocking movement of the lever 11 upon its fulcrum or pivot point longitudinally of the valve stem 13. Formed on the opposite sides of the lever 11 and adjacent the aperture 14 therein are the pairs of pivotal bearing lines 15. The lower pair of pivotal bearing lines 15, or the pair formed on the under side of the lever 11, are adapted to engage and bear against the upper end of the sleeve 16 surrounding the valve stem 18 between the valve 9 and the lever 11. To hold the valve stem 13 in position I relative to the-lever and the lever in operative position relative to the body 1, the nuts 17 are threaded on the upper and free end of the valve stem and engage with the upper pivotal bearing lines 15 on the lever,

thus providing a suitable bearing for. said pivotal bearing lines. As here shown, the nuts 17 are threaded on the valve stem, however, they may be adjustably secured thereto in any suitable manner that will maintain the pivotal bearing lines 15 against their bearings. It is desired to have the nuts or bearings 17 adjustable so that play between the bearings and the pivotal bearing lines 15 may be had or to prevent lost motion of the lever with respect to the valve stem 13. I

The cap 7 is provided on its inner or under side with a guideway 18 suitably formed thereupon which is adapted to receive the upper end of the valve stem carrying the nuts or bearings 17 for guiding the movement of the valve stem. It will also be.

16 to provide a water-tight connection joint and prevent the passage of fluid into the upper portion of the bore 2 in which the valve mechanism is arranged. The helical spring 20 surrounds the sleeve and valve stem 16 and 13, respectively, between the gasket 18 and the lever 11 and is adapted to exert a tension upon the lever to operate thesame for normally seating the valve 8 upon the seat 9. The spring 20 also tends to hold the gaskets 19 in position.

' From the above construction it will be seen that the valve stem 13 extends through an opening in the operating lever 11, thereby holding the lever in position in the head which has a loose pivotal connection intermediate its ends therewith for operating the latter. The removable cap 7 aflords access to the valve mechanism and permits the re moval of the same from the siphon head 1, as well as providing a guide means for the valve stem.

.Figs. 7 8, 9 and 10 illustrate a modified at 21 and since the valve stem 13 extends through the aperture 1% of the lever 11*, the

edge of said-aperture is adapted to engage with said chamfered end 21 ,The nuts 17 are threaded on the upper end of the valve stem 13?, the lower nut being chamfered con responding to the upper end of the sleeve 16 .and adapted to engage with the opposite edges of the opening 1 1 in the lever 1-1. The chamfered or beveled ends of the sleeve 16'? and the nuts 17 permit a rocking movement of the operating lever with respect to the valve stem in a manner similar to that'disclosed in Fig. 1. The upper end of the valve stem 13 and the nuts 16 are adapted to be received in the guideway 18 provided in the cap 7 From the foregoing, a full and accurate description of the invention may be had. However, it is to be understood that certain changes as to the exact and precise construction of parts may be resorted to that fall within the legitimate scope of the appended claims. 7
